STAND FOR PHONOGRAPH-RECORD PRESSES.

Specification of Letters Patent.

Patented Apr. 1, 1919.

To allwhom it may concern Be it known that I, FRANK L. CArPs, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Stands for Phono:

, graph-Record Presses, of which the following-is a specification. e

In the manufacture of phonograph records or similar flat molded objects by the compression of plastic material between mat rices, it is essential, when the same are removed from the press, to remove the diesv and to separate the molded record from the matrices ormolds and also to collect and preserve the surplus plastic material for re-use.

The stand of the present invention is adapted to serve these purposes in a convenient and eflicient manner.

- The object of the invention consists in the improvement of stands of the class referred to in numerous important respects, and with such object in view, my invention consists in the construction, parts, improvements and combinations herein set forth andclaimed.

In the drawing forming part of this specification and wherein the same reference'numerals are used to designate the same parts throughout, Figure 1 is,a top view, partly in section, of one form of stand embodying my invention. Fig. 2 is a perspective view 'of a knocking block. Fig. 3 is a vertical sectional view taken on line 3-3, Fig. 1, and. Fig. 4 is a perspective view of the adjustable shelf with which stands embodying my invention are preferably provided.

Reference numeral 10 designates the hopper of my improved stand and 11 the legs. In the form. shown the hopper is a metal casting and the legs are rods or bars of iron or other metal secured in openin s 12 in the hopper body 10, but it will be 0 vious that 'other materials may be used and that the legsmay be connected to the hopper in other ways. The hopper is provided with a substantially; circular bottom opening 13 beneath which the removable scrap can 14 may be placed. This scrap can being received entirely under the hopper and within the space between the legs-1 1, is entirely out of the way, and" the space immediately over the scrap can being utilized for the knocking block and hopper, results in a very considerable economy of space which is important.

queue in a room containing large numbers of record presses. The knocking block. 15 is supported over the hopper 10 and the opening 13 therein, and in the form shown the hopper 10 isprovided with diagonal cross-bars 16 which serve to support the knocking block and are provided with retaining means, as the corner pieces 17 17, and the side flange 18 having the right-angled projections 19, 19 which in effect form two corner blocks con- .nected together by the flange 18. The knocking block may rest directly on the cross-bars 16 or may have a plate or floor 20 on which it is supported and which may be cast in tegral with the hopper and the cross-bars 16, and when such plate 20 is provided it is preferably cut away on its sides between its corners, as shown at 21, 21. The provision of these cut-outs affords a ready passage for any trimmings or surplus material from the record to pass readily through the opening 13 into the scrap can 14. The knocking block 15 is substantially of parallelepipedon form and is provided with short legs 22, 22 which rest within the corner supports 17, 18 and 19 by which it is held against movement and is preferably recessed, as shown at 23, Fig. 3, so as not to be unnecessarily heavy, while at the same time it is sufiiciently massive to serve as a block on which to strike the molds and to separate them from the records. Its upper surface projects above the hopper so as to present a solid surface on which the dies are struck to separate them. The block 15- preferably has a recess 24 on its upper side which is provided for 'the'purpose of receiving a center pin made use of in pressing recdrds. If desired, the block 15 may be formed integrally with the hopper, as by castin them together. After the die is and removed, the matrices and record adhering thereto may be laid on the knocking .block 15, with the center pin over the recess 24, and the center pin, being driven out with a suitable tool, as a small punch,

falls into the recess 24 in the knocking block,

from which it may be removed. The record is then readily separated from the matrices and the scrap and trimmings fall into the can 14.

The rear legs 11 of the stand are preferably extended upward, as shown at 11, and the shelf 25 secured thereto. Said shelf is preferably made slidable up and down on the members 11 and may be secured in place able purpose,

in any desired position, as by means of the be used for any suitas torecelve record material, I

set-screw 26. It may completed records, etc. o

The operation of the device has been described in connection-with the description of the preferred form of construction.

1 It is to be understood that the form, of

device illustrated is for the purpose of affording an understanding of my invention,

porting said knocking block, said hopper being provided with a discharge aperture beneath said knocking block. i

2. The combination of a hopper, legs therefor, a knocking block, means in the hopper for supporting the knocking block so that the top thereof projects above the hopper, and said hopper being provided with a central discharge aperture, and means therefor," a" knocking block, means in -the hopper for supporting beneath said discharge aperture for collecting trimmings, scraps and the like;

3. The combination of a hopper, legs the knocking block, being adapted to Tesaid supportingmeans receive said knocking block and movably to hold it against lateral movement, and a can under the hopper discharge and Within the space between its legs for receiving material falling into said hopper.

- 4. A"stand of the class described comprising a hopper provided with a discharge aperture, a knocking block, supporting knocking block and provided with upstanding marginal means for preventing lateral displacement of the knocking block.

- means in the hopper for supporting the r 5..In a stand of the class described, the

combination of a-hop'per provided with a central discharge opening, diagonal cross members in said hopper and extending above said opening, a knocking block, and means on said members for removably supporting said knocking block and holding it against lateral displacement..

6. In a stand of the class described, the combination of a vhopper having acentral discharge opening, a knocking block supported in said. hopper and extending thereabove, a can under the hopper for collecting trimmings and scraps of record material,

the hopper beingprovided with legs which extend upwardly beyond the top thereof, a shelf slidable on said legs, and means for adjustably securing said shelf to said extensions of the legs and thereby adjusting the height thereof.

In, testimony that I claim the foregoing,

- hereto set my hand, this 18th'day of August, 1917.
